OBJECTIVE To evaluate the clinical efficacy of Chaihu anxin capsules in the treatment of mild-to-moderate depression， analyze the influencing factors of its efficacy, construct a nomogram prediction model.METHODS Patients with mild-to-moderate depression treated at The First Hospital of Hebei Medical University from May 1， 2023 to March 10， 2025 were retrospectively included and categorized into Chaihu anxin capsules group and milnacipran group according to treatment regimen. Propensity score matching （PSM） was used to balance baseline characteristics， and treatment efficacy was compared after 8 weeks， including 24 Hamilton Depression Scale （HAMD-24） scores and changes， Hamilton Anxiety Scale （HAMA） scores and changes， and treatment response rate after 8 weeks of treatment. Patients receiving Chaihu anxin capsules were further classified as responders or non-responders based on the occurrence of treatment response. Univariate and multivariate Logistic regression analyses were conducted to identify the influencing factors of treatment response， and a nomogram model was constructed to predict the probability of treatment response， its predictive performance was evaluated using receiver operating characteristic （ROC） curves， calibration curves， and decision curve analysis.RESULTS A total of 297 patients were included before PSM， including 196 patients in the Chaihu anxin capsules group and 101 patients in the milnacipran group. After PSM， each group included 44 patients. After PSM， the HAMD-24 scores and HAMA scores at 8 weeks after treatment in the Chaihu anxin capsules group， as well as the HAMD-24 scores in the milnacipran group， were significantly lower than their respective baseline values （ P ＜0.05）； the change in HAMA score in the Chaihu anxin capsules group was significantly greater than that in the milnacipran group （ P ＝0.04）. Multivariable Logistic regression identified age， total bilirubin， and baseline HAMD-24 score as independent predictors of treatment response （ P ＜0.05）. The area under the ROC curve of the constructed nomogram prediction model was 0.72 （95% confidence interval： 0.637-0.799）， and the corrected Brier score was 0.143 （95% confidence interval： 0.112-0.176）； compared with the “all intervention” and “all non intervention” strategies， applying this nomogram prediction model could achieve higher net benefits within the threshold probability range of 8% to 37%.CONCLUSIONS The efficacy of Chaihu anxin capsules in improving mild-to-moderate depression is comparable to that of milnacipran， and it has certain advantages in improving anxiety symptoms； age， total bilirubin， and baseline HAMD-24 score are independent influencing factors for the treatment response of Chaihu anxin capsules. The nomogram prediction model constructed based on these factors has good discrimination， calibration， and clinical applicability.

With the increasing demand for dynamic,real-time and rapid qualitative analysis of chemical composition in areas such as emergency response and space exploration,chip-scale mass spectrometers have attracted significant attention.These devices are expected to drive the integration of mass spectrometry with micro/nano-fabrication and intelligent sensing technologies,fostering profound innovation and breakthroughs in analytical chemistry.As an excellent mass analyzer,the ion trap exhibits numerous advantages,and its miniaturization creates favorable conditions for the high-density integration of miniature mass spectrometers.However,the reduction in ion storage capacity may compromise its sensitivity and dynamic range,rendering the study of ion unidirectional ejection in highly miniaturized ion traps of significant practical importance.In this work,a research was conducted on achieving efficient ion unidirectional ejection while maintaining high mass resolution in the extremely miniature hyperbolic linear ion trap(M-HLIT)with a field radius of 1 mm,and an electric field compensation method was proposed,which combined asymmetric electrode stretching and unbalanced RF voltage to achieve high-precision optimization of the electric field composition.Simulations showed that in an ideal structure,this method achieved 100％unidirectional ejection efficiency with the mass resolution of 518,significantly outperforming traditional asymmetric structure method(365)and unbalanced voltage method(321).Following the introduction of ion ejection slots,further optimization through bidirectional stretching and electrical parameters improved the resolution to 790 while maintaining a unidirectional ejection efficiency of 93％.This method eliminated the requirement for additional excitation voltage,offering an ideal solution for the miniature mass analyzer with high detection performance of chip-level mass spectrometers.

Objective To investigate the risk factors associated with perioperative hemodynamic disorders(HD)following carotid artery stenting(CAS)for carotid sinus stenosis.Methods The clinical data of 71 patients who underwent CAS for carotid sinus stenosis were retrospectively analyzed.The patients were divided into the HD group(20 cases)and the non-HD group(51 cases)based on the occurrence of HD,and inter-group comparisons along with binary logistic regression analysis were performed.All patients underwent carotid computed tomography angiography(CTA)prior to surgery.Results In the HD group,the duration of dopamine usage ranged from 9 to 71 hours,the mean age was(73.90±5.24)years old(P=0.038),and the average length of hospital stay was(9.60±3.63)days(P＜0.001).Univariate logistic regression analysis revealed that plaque calcification(P=0.035),annular calcification(P＜0.001),plaque length(P=0.012),and the degree of stenosis(P=0.014)were associated with perioperative HD after CAS.Multivariate logistic regression analysis identified annular calcification and plaque length as independent predictors of perioperative HD(P＜0.05).Conclusion Age,plaque calcification,annular calcification,plaque length,and the degree of stenosis are closely associated with the occurrence of perioperative HD after CAS in patients with carotid sinus stenosis.Annular calcification and plaque length are independent risk factors for the occurrence of HD.

Objective:To assess the baseline direction,mechanisms,and heterogeneous manifestations of the spillover effects of healthy city pilot policies on healthy aging in rural areas.Methods:Utilizing five-wave panel data from the China Longitudinal Aging Social Survey(CLASS)spanning 2014-2023,a difference-in-differences model was constructed to examine whether significant changes occurred in healthy aging levels within rural areas following policy implementation.Results:The healthy city pilot policy exerted significantly positive spillover effects on healthy aging in rural areas,primarily manifested through improvements in older adults'psychological and social health.These effects operated via enhanced medical service utilization and improved health behaviors in later life.Rural older adults with higher education levels,those co-residing with children,and those residing in economically developed or medically well-resourced areas experienced greater benefits.Conclusions:Healthy city pilot policies can transcend urban boundaries and benefit rural healthy aging through policy spillover effects.Future policies should focus on:deepening the integration and deployment of high-quality medical resources to rural areas;increasing investment in constructing age-friendly supportive health environments in rural settings;and enhancing targeted health intervention strategies for relatively disadvantaged groups—thereby improving the equity and inclusiveness of policy spillovers.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

OBJECTIVE: To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries. METHODS: We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage. RESULTS: After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996. CONCLUSION Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

In recent years, significant progress has been made in the structural optimization and mechanistic research of antibody-drug conjugates (ADC), with multiple clinical trials for prostate cancer underway and demonstrating broad clinical application prospects. Compared with traditional chemotherapy and immunotherapy, ADC combines the targeting specificity of monoclonal antibodies with the potent tumor-killing ability of chemotherapeutic drugs, offering potential therapeutic options for prostate cancer patients. Currently, four prostate-specific membrane antigen-targeted ADC have entered the clinical trial phase, but their clinical efficacy and safety profiles exhibit significant differences. Additionally, the identification of novel molecular biomarkers such as STEAP1, TROP2, and B7-H3 has provided potential targets for the development of the next generation of prostate cancer ADC, with relevant candidate drugs having progressed to clinical trials and their research outcomes highly anticipated. Although no ADC has been approved for clinical treatment of prostate cancer, in-depth analysis of the current challenges and future development directions in ADC research will provide theoretical support and innovative insights for advancing these agents in prostate cancer research.
